Counter-Strike co-creator and Valve game designer Jess Cliffe has been booked for sex exploitation of a child, Seattle local news KIRO 7 reports.

Police have not commented yet, but KIRO 7 reports Cliffe has not been charged yet. The arrest occurred at 1:17 AM this morning at the Seattle Southwest precinct police department.

Cliffe has been an employee of Valve since 2003 after creating Half-Life mod Counter-Strike in 1999 alongside co-creator Minh Le. Valve hired Cliffe and obtained the rights to the game, which has become one of if not the most popular multiplayer shooter in the world in the fifteen years since.

“We are still learning details of what actually happened,” Valve’s Doug Lombardi told us. “Reports suggest he has been arrested for a felony offense. As such we have
suspended his employment until we know more.”
